Airborne bacteria from the cattle source were generated and released into a small-scale test chamber (1.5 m3) with different strategies according to the different objectives in decay tests and simulated sterilization tests. Increasing with the UVA radiation gradients (0, 500, 1000, 1500 \u03bcW cm\u22122), the average decay rate of total curable airborne bacteria ranged from 2.7% to 61.6% in decay tests. Under the combination of different UVA radiation intensities (2000 \u03bcW cm\u22122 in maximum) and radiation durations (60 min in maximum), simulated sterilization tests were conducted to examine the potential use of UVA radiation for air sterilization in animal houses. With the dynamic inactive rate (DIR) ranging from 17.2% to 62.4%, we proved that UVA may be an alternative way to reduce the indoor airborne bacteria in cattle houses if applied properly. Similar effects would be achieved using either a high radiation intensity with a short radiation duration or a low radiation intensity with a long radiation duration.<\/jats:p>","DOI":"10.3390\/ani14243649","type":"journal-article","created":{"date-parts":[[2024,12,18]],"date-time":"2024-12-18T03:40:56Z","timestamp":1734493256000},"page":"3649","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Decay of Airborne Bacteria from Cattle Farm Under A-Band Ultraviolet Radiation"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1451-557X","authenticated-orcid":false,"given":"Luyu","family":"Ding","sequence":"first","affiliation":[{"name":"Information Technology Research Center, Beijing Academy of Agriculture and Forestry Sciences, Beijing 100097, China"},{"name":"National Engineering Research Center for Information Technology in Agriculture (NERCITA), Beijing 100097, China"},{"name":"National Innovation Center of Digital Technology in Animal Husbandry, Beijing 100097, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qing","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Agricultural Structure and Bioenvironmental Engineering, College of Water Resources and Civil Engineering, China Agricultural University, Beijing 100083, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-1718-6707","authenticated-orcid":false,"given":"Ligen","family":"Yu","sequence":"additional","affiliation":[{"name":"Information Technology Research Center, Beijing Academy of Agriculture and Forestry Sciences, Beijing 100097, China"},{"name":"National Engineering Research Center for Information Technology in Agriculture (NERCITA), Beijing 100097, China"},{"name":"National Innovation Center of Digital Technology in Animal Husbandry, Beijing 100097, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ruixiang","family":"Jiang","sequence":"additional","affiliation":[{"name":"Information Technology Research Center, Beijing Academy of Agriculture and Forestry Sciences, Beijing 100097, China"},{"name":"National Engineering Research Center for Information Technology in Agriculture (NERCITA), Beijing 100097, China"},{"name":"National Innovation Center of Digital Technology in Animal Husbandry, Beijing 100097, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chunxia","family":"Yao","sequence":"additional","affiliation":[{"name":"Information Technology Research Center, Beijing Academy of Agriculture and Forestry Sciences, Beijing 100097, China"},{"name":"National Engineering Research Center for Information Technology in Agriculture (NERCITA), Beijing 100097, China"},{"name":"National Innovation Center of Digital Technology in Animal Husbandry, Beijing 100097, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9415-8527","authenticated-orcid":false,"given":"Chaoyuan","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Agricultural Structure and Bioenvironmental Engineering, College of Water Resources and Civil Engineering, China Agricultural University, Beijing 100083, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qifeng","family":"Li","sequence":"additional","affiliation":[{"name":"Information Technology Research Center, Beijing Academy of Agriculture and Forestry Sciences, Beijing 100097, China"},{"name":"National Engineering Research Center for Information Technology in Agriculture (NERCITA), Beijing 100097, China"},{"name":"National Innovation Center of Digital Technology in Animal Husbandry, Beijing 100097, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,12,18]]},"reference":[{"key":"ref_1","unstructured":"Clauss, M.
